Battery pack catches fire inside Rivian's Illinois assembly plant

A fire broke out at Rivian’s Normal, Illinois assembly plant last weekend due to a faulty battery pack. The town of Normal posted the news on its official government website, and it was brought to our attention via Automotive News’ report of the fire.

The fire was contained to a single faulty battery pack that was being tested in Rivian’s battery testing area of the plant. The battery was going through thermal runaway when firefighters arrived. Because of this, the firefighters kept applying cold water to the battery long after the initial flames were extinguished to keep it cool and prevent it from catching fire again. Firefighters from Bloomington, Indiana were called in to assist the Normal firefighters to assist with manpower at the large facility. After the fire was deemed fully out, the responders on scene began ventilating the building to make it safe and operable once again.

Automotive News received an explanation from Rivian on the incident, stating that the battery pack had already been deemed faulty prior to the fire.
